What matters
Choose a formula and strength your skin can tolerate; more vitamin C is not automatically better. Opaque packaging helps protect formulas from light, and sunscreen remains essential.
Who this is for
These picks suit shoppers looking to brighten dull or uneven-looking skin, from beginners to experienced vitamin C users. If your skin is reactive, start cautiously and consider checking with a dermatologist.
The picks, one by one
Best overall: Obagi Medical Professional-C Serum 10%
Fortune’s 2026 testers named Obagi their overall pick, noting it felt hydrating, gave skin a glow and did not pill under sunscreen or makeup. The 10% strength is a more approachable starting point than its 15% and 20% versions. The reviewer used a few drops in the morning and found it spread easily, though it took a few minutes to dry. Its dark glass bottle helps shield the formula from light. Obagi also offers higher strengths if you already know your skin tolerates vitamin C. Skip it if fragrance bothers you: testers noted a strong floral scent.
Good to know: It costs far more than the other two picks and has a noticeable fragrance.
See on AmazonBest value: TruSkin Vitamin C Serum for Face
Fortune picked it for value, and testers found it lightweight, hydrating and easy to layer with moisturizer, sunscreen and makeup. It is substantially cheaper than Obagi. The formula uses sodium ascorbyl phosphate, a vitamin C derivative, rather than L-ascorbic acid. A tester with combination skin said it absorbed quickly and left her skin feeling hydrated and brighter without tingling. The brand does not disclose the vitamin C concentration, so it is less transparent for shoppers comparing strength. Botanical extracts may bother some sensitive skin.
Good to know: Its vitamin C concentration is not disclosed.
See on AmazonCheapest that's still good: Naturium Vitamin C Complex Face Serum
At about $16 on Amazon in a recent comparison, it was the lowest-priced pick here with a reviewer recommendation and a formula listing both L-ascorbic acid and vitamin C derivative. The review highlighted its pump packaging and budget-friendly price. The comparison lists a 22% vitamin C complex alongside vitamin E and hyaluronic acid. Its pump is convenient, and the formula is fragrance-free, according to the review. That high stated concentration may be too much for sensitive or acne-prone skin, so introduce it gradually and patch test. Choose another pick if you want a gentler beginner formula.
Good to know: Its high concentration can irritate sensitive skin.

Recent reviewers assessed application, texture, layering, skin feel and perceived brightening, with some comparisons also drawing on longer-term editor testing.
